7 HYGIENIC HOT-PLATE.

Specification of Letters Patent.

Patented Uct. 26, 1915.

Application filed May 11, 1914. Serial N 0. 837,628.

To all whom it may concern:

Be it known that I, GOLLADAY LAKE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Hygienic Hot- Plates, of which the following is a full,-

tured from pressed sheet metal.

Another object is to provide a heat distributer Which shall act as a crematory to burn the by-products of combustion beneath the distributer.

Another object is to so construct the dis tributer as to allow free circulation of the heated gases through it, causing them to be evenly distributed over the bottom of the cooking utensil, at the same time allowing them to pass freely through the distributer and be cremated while the utensil is in place thereon.

Another object is to prevent the waste of heat at the base of the burner.

My invention is hereinafter more fully described in connection with the'drawings and the essential characteristics set forth in the claims.

Figure 1 1s a perspective view of my device on which a cooking utensil is lndlcated in broken lines; Fig. 2 is a. central vertical sectiontaken substantially on the line 2'2 of Fig. 1; Fig. :3 is a bottom 'plan of the distributer; Fig. 4 is a vertical section of a portion of the edge of the plate showing a modified construction on an enlarged scale.

Referring to the parts by numerals; 5 indicates a plate made of sheet metal having a substantially flat top surface and a dow wardly turned skirt 6 forming a vertical the bead 7 which brings the plate 10 above the top of the stove Or gridiron, indicated at 12, or other support on which the distributor may rest,- providing a chamber-like space beneath the plate 10.

At the center of the plate 5 is formed a depression 15, from which radiate fines or grooves 16 communicating with this central depression and extending to the outer edge of the plate. The depression 15 and the -grooves 16 are formed by pressing them into the plate while it is being formed. In

the bottom of the grooves is made a series of openings 18 adapted to allow the heated air and gases to pass through the plate and out along the grooves, beneath a cooking utensil setting on the plate. The grooves are preferably widened slightly around the openings 18 as shown at 19. It will be noted that the upper edge of the flange 11 abuts the under side of the groove portions 16,

thereby holding the plate 10 against upward movement. a

In the modified form shown in Fig. 4, the plate 10 is provided with a downwardly turned flange 25, formed with a small bead 26, and the skirt 6 into which this flange fits, is curled around the small bead 26, as shown at 27. The plate 10 may be further prevented from upward movement by providing an inwardly pressed annular bead 29 in the skirt 6, this bead being just above the edge of the plate 10.

Around the outer edge of the plate 10, adjacent the flange 11 are made openings 20 allowing the heated air and gases to pass upwardly from beneath the plate 10 into the chamber 21, between the plates 10 and 5.

In operation, the cooking utensil 24L (indicated in broken linesin Fig. 1) is placed upon the upper part ofthe distributor which is standing on the stove or over a suitable burner, the heated air and gases come up against the under side of the plate 10 and spread outwardly to the periphery of the distributer, but are prevented'from escaping gases pass upwardly through the openings bringing the heated gases away from the centerto the outer edge of the, cooking utensil and allowing themto act efficiently. This also facilitates delicate cooking, in that ex cessive heat in the form of a blaze, cannot play onthe cooking. utensil, and the superfluous heated gases may pass out of these fines.

It will be seen rmmthe foregoing descrip tion thatI have provided a distributer well adapted for many uses, having two compartments for the heated air and gases, by which I accomplish the objects setforth and which may be said to be hygienic, as, it does not allow the poisonous products of combustion to escape into the room, but entirely consuines them before they escape from the flues 16. i p

Although I have shown and described a particular form of hot plate, embodying my invention, it is to be understood that other modified forms maybe used without departing from the spirit of my invention.

What I claim is: I

1. A he ating device comprising a substantially flat upper and a lower plate spaced apart, edge wall connecting said plates, a supporting wall projecting beneath the lower plate adapted to form a bafiie, depressed radial grooves in the upper plate having openings through the plate at the bottom of the grooves, andan annular row of openings through the bottom plate adjacent the supportingwall, said openings be ing out of vertical alinement with the first mentioned openings.

2. A heat distributing device comprising an upper plate and a lower plate spaced therefrom, an edge wall formed on the upper plate and extending downwardly be- 'neath the lower plate and having an inturned bead to hold the lower plate, an annular row of openings adjacent the edge of the lower plate, depressed radial grooves formed in the upper plate and extending upper plate and extending downwardly beneath the lower plate forming an annular baflie and having an inturned bead to hold the lower plate, a flange formed on the lower plate engaging said wall, an annular row of openings adjacent the edge of the lower plate, depressed radial grooves formed in the upper plate and extending to the outer edge thereof, and openings through the upper plate in these grooves.

4. In a heating device comprising upper and lower plates spaced apart, an edge wall connecting said plates and an annular ballle formed around the outside edge of the lower plate, an annular row of openings through the lower plate adjacent this bafile, outwardly extending grooves in the upper plate, and openings through the upper plate in said grooves arranged in a central zone, whereby heated gases are deflected by said battle and caused to pass through said annular row of openings and then toward the center of the plates between the same, then upwardly through the openings in the up per plate and outwardly along said grooves.

5. In a heating device, the combination of upper and lower plates spaced apart, an edge wall connecting said plates, an annular baflie formed around the space below the lower plate, an annular row of openings through the lower plate adjacent to this bafiie, the intermediate portion of the lower plate being impervious, radial depressions in the upper plate, and openings through the up er plate in such depressions.
